COIN OPERATED VENDING MACHINE Emma A. Laughery, Chicago, Ill.

Application March 14, 1935, Serial No. 11,089 Renewed August 30, 1937 4Claims. (01. 312-56) This invention relates to an apparatus fromarticles to be vended, such as newspapers A, are which newspapers,periodicals or other selected placed upon a suitable inclined runway I4,and commodities may be dispensed. these are pressed forward by afollower plate An object of this invention is to provide means I5 towhich are pivotally mounted rollers I5 5 for effecting the easy egressof a newspaper or which operate on the runway I4. The plate 15 is otherarticle from a Vending machine when opfurther pressed by means offingers l6, I! which erated as intended, but which prevents the inareurged forward by means of springs l8, l9,[ sertion of any implementthrough the delivery respectively. chute for withdrawing articlestherethrough. These newspapers A or other commodities are Another objectis to provide an improved mechpressed forward against a front plate 20which anism for lifting a single article with each actu carries a ledge2| upon which the forward article ation of the mechanism after releaseof the same rests. In front of the plate 20 are guides 22 on depositingthe proper coin or coins. whereon slides a carriage 23 (Fig. 2) to whichis Another object is to provide means for returnattached a chain 24passing over a pulley 25.

An operating knob 29 closing the coin slotagainst the insertion of coins connected to the truck extends throughthe slot when operation of the dispensing mechanism has to the frontside of the machine housing. Thus once been started. it will be seenthat the chain and associated parts These and other objects, as willhereinafter are entirely closed within the housing with the appear, areaccomplished by this invention which exception of the operating knob soas to be prois fully described in the following specification tectedagainst tampering and against the eleand shown in the accompanyingdrawings, wherements. in- The lifting of the newspaper or other article,Fig. 1 is a perspective view of a coin operated particularly when nottoo heavy, is accomplished, 3O vending machine for newspapers and thelike; as in the patent above referred to, by means of a 50 Fig. 2 is anenlarged section on the line 2-2 series of pins 30 which are carriedupon a rock of Fig. 1; shaft 3|, each of the pins operating in a slotFig. 3 is a detail in elevation of a pawl for lift- 32 (Fig. 6) Themethod of mounting and operating newspapers from the machine, the pawlbeing ing these pins has been fully described in the 35 here shownlocked in an inoperative position; above mentioned patent so that itwill not here 35 Fig. 4 is a similar view showing the pawl in opberepeated. One of the aspects of the present erative position; inventionrelates to the form of these pins. By Fig. 5 is an end view of theneedle shown on making them pointed, tapered and of triangular line 5 ofFig. 2; cross section with the fiat portion of the triangle 40 Fig. 6 isan enlarged vertical elevation, partly on top (see Fig. 5) it is foundthat they are much 40 in section, showing the coin chutes and associatedmore effective for lifting the articles without tearparts; and ing orinjury.

Fig. 7 is a fragmentary section on line I of Avertical member 32(Figs.2and 6) is secured Fig. 6. at each side of the housing and. hasaseries of My present invention is concerned with various teeth on itsfront edge adapted to be engaged 5 features of improvement applicable tothe type of by a pawl (not shown) acting in a well-known vending machinewhich is shown and described in manner to prevent the carriage fromreturning, Patent No. 1,638,413, granted Aug. 9, 1927. Many once it hasstarted, until the carriage reaches the details of construction theredisclosed are thereupper limit of its travel.

0 fore not repeated in the present drawings. For heavier articles, suchas magazines, it may In the machine here illustrated I utilize a bedesirable to supplement the pins with pawls housing having a front wall8, a rear wall 9, a 33 (Figs. 3 and 4), each of which is pivotallybottom l0, end walls I l, and a hinged top I2 mounted on a pin 34secured to the carriage 23. adapted to swing about a pivot I3 and to besuit- Each pawl is formed with an ear 35 extending ably locked by ameans not shown. A stack of from one side to engage the bottom of thecar- 55 riage, whereby to serve as'a'limiting stop to the outward swingof the pawl into'operative position, as shown in Fig. 4. Alongside eachpawl lies a locking member 36 having a slot 3'! through 38 connects alug 36 on the. member 36 with a lug 33 on each pawl." "Ihis spring urgesthe pawl 33 toward its operative. position, and the member 36 toward theloweredpositionof Fig. 4.

The member '36alsohas a laterally extending lug 36 which is adapted toengage ;a' notch "59 which is pivotally mounted on a pintle'60 (Fig. W

' 2) In connection with the shield is a springil 33 in the pawl, asshown in Fig. 3, to hold the pawl in an inoperative position.

It will be apparent that when a A" is to be vended, the lifting pawls'33 will be released so as to advance to operative position. At othertimes when lighter articles are article, the springs 38. yieldingsuffieiently for this purpose. 1 r

In Figs. 6 and? the coin chutesare shown in detail Thus the chute 39, 40may be a penny chute, while the chute 4|, 42 may be a nickel 7 chute.The number of pennies to. be taken through the penny chute may beadjustably'fixed by the position of a coin adjusting lever 43 so as toreceive no pennies, or one or morer pennies; As shown in Fig. 6, thislever is adjusted to receive two pennies 44, and if another'penny as'45: --.is inserted it will pass down an overflow chute A6 to a returnchute 41 (Figs. 1 and '7) where the pennies will be returned to'theoutside whereby they are returned to the depositor. Similarly, if therebe the insertion 'of a nickel 48 more ,than is required for thearticleto be vended, that nickel will be passed down the nickel overflow slot49 to areturn'chute .50 (Figs. 1 and'6) for return to the. depositor. iI

Another aspect of this invention relates to a means for closing the coinslot at the front of the .box so that no more coins can be insertedafter thecarriage23 has started its upward movement. To do this I haveprovided a lever 51 'pivotally mounted at 52 which engages and ispressed'down from the dotted line position to the full line position ofFig. 6 by means'of. a bearing 53, or other partof the carriage when thelatter is down.

The lever '5! is connected bymeans of a link .54 with a lever 55 nearthe top of the machihe,
